Kevin has been over there TWICE and has been patient as the first time, she refused to let him in.

She will finally have A/C for the summer and will not be an "elderly person who died of heatstroke" story on the news. Could not recommend him more! Very reasonable and trustworthy!

If he feels that your needs are better suited for another professional he will tell you so, which I am thankful for because no one wants to pay for someone to play around with you home.

My AC unit completely stopped working last night and I called the owner, Tom, at 8pm and he…read moreactually answered. He was able to come out the very next day and fix the problem. What really stood out was how detailed and honest Tom was about the work. He explained everything clearly, didn't try to upsell me on anything unnecessary, and made sure I understood exactly what was done. I believe Tom is the kind of person you can genuinely trust. I'll definitely be reaching out to him for any future HVAC needs. If you're looking for someone reliable who actually cares about doing the job right, call this company!

Diagnosed the problem right away; fixed it with an efficient, cost-effective solution; taught me along the way about what he was doing & why and other things I could do to help my AC unit. He was in & out in less than 15 minutes. And I'll be calling again in September for my heat!! Highly recommend!!

Full disclosure, I wanted to give 4.5 instead of 5, because they are expensive, BUT, so is everyone…read moreelse, AND they did right by me in my instance, so I went with 5 instead of 4. I was having an issue with my zoned HVAC. My dampers NEVER closed, and no matter what the temperature was in one zone, if the other called for AC/heat, the other zone got it as well. This led to my upstairs being like 6/7 degrees different than the downstairs, and a horribly inefficient HVAC system running non stop. I'm pretty handy, and did all of MY DIY troubleshooting, and narrowed it down to a board issue, but since I couldn't figure it out, I called in the big guns. I was a little annoyed when I first called McCallisters, because the receptionist seemed absolutely hellbent on getting my payment info before scheduling me, but I'll get to that in a minute. Eventually, they sent out a tech, Kadim, that came to take a look. Kadim showed up, and despite spending a GOOD amount of time with my system, he couldn't figure out what was wrong. BUT, he came to the same hypothesis that I did, suggesting it was a board issue. He even stated that he wasn't SURE, and therefore didn't want to tell me anything conclusive, which I appreciated. He told me that Joe, the service manager, would reach out to me soon, after they discussed the issue and looked at the pictures Kadim took. About that payment stuff; I got a call from Joe, who informed me that they were going to send out another tech with a little more zoned HVAC experience, and also verified that they didn't charge me for the diagnostic the first time, since they never actually diagnosed the problem. Again, a good, honest business practice. SO, today: second tech shows up (Dave), does some diagnostic, and verifies that it IS a board issue, but that the board isn't bad, just had one wire incorrect! He had me test the system, and I finally got to see the zone 1 dampers close! Not only does it fix the issue, and will start saving me money by not having the AC run constantly, but I didn't have to buy a new board and pay the labor to have it all installed. The full cost was more than I would have liked for a diagnostic, and to move one wire, but it fixed the issue, and actually saved me money in the long run. So I'll chalk it up as just the cost of being a homeowner. Either way, I'm super happy with how the whole situation with McCallisters played out. They were quick, (both visits/phone calls etc, took place over like 4 business days), extremely polite and professional, and thorough.

I immediately called the gas company and they came and shut off the gas line. It's the dead of the winter and now I have no heat. I didn't know where to begin. I checked the internet but nothing jumped out at me. I went on yelp and began reading reviews and I ran across Lawrence heating & air. I called spoke to a woman who was very pleasant and told me a tech could come out to assess the boiler to see if it was still usable. Joe came and he looked at it and said it it's a hazard. With all the rust and corrosion and not to mention whatever was on fire. He said it needed replacing. He talked to me about the options and stated I would get an email from the owner of my options. 30 mins later the email was there and everything was included. All the info I needed to know about the unit, specs, warranty, parts/tubing for replacement, price. It was a proposal. I reached out to Lawrence with my questions and he answered right away. I also stated my elderly dad lives with me and elderly need service as soon as possible. That was no problem. He sent me payment options as well. Once I accepted the proposal and date was locked in and they techs came the next day on time. Randy showed up first, then Joe & Chaly. They immediately put down floor draping and loaded all of the supplies , pipes , boiler, etc. They opened all the radiators starting at the top. All of them were pleasant and very Knowledgeable about their job. Any questions I asked Randy explained. They cleaned up behind themselves and made sure everything was put back in place. Once they were done Randy told me about my new unit and what was removed and put in. This company made the entire stressful event so much more easier, like a weight had been lifted. My house is warm and cozy thanks to everyone involved .. Great teamwork ! I would definitely recommend !!! Thank you so much to everyone that played a part in getting me back up in running !!
